플로팅 건축물은 현장 시공을 최소화해야할 필요성으로 인하여 모듈러 시스템의 적용 가능성이 높다. 그러나 국내의 경우 모듈러 시스템을 적용한 사례가 적을 뿐만 아니라 모듈러 시스템의 시공과 관련된 가이드라인도 없다. 모듈러 시스템의 적용이 상대적으로 보편화된 국외 가이드라인 사례 연구를 통하여 플로팅 건축에서 모듈러 시스템 시공계획을 위한 시사점을 얻고자 하였다. 문헌자료 및 인터넷 자료 등의 검색을 통해 국외 가이드라인 사례를 수집하고 이를 분석하였다.

유럽에서 지어진 플로팅 건축물을 중심으로 상부 시설에 적용된 모듈러 시스템을 분석하여 이를 유형에 따라 분류하였다. 플로팅 건축 상부시설에서 모듈러 시스템 적용 유형은 단위 공간 모듈러를 적용하는 경우와 단위 건축물 모듈러를 적용하는 경우로 나누어 볼 수 있었고, 단위 공간 모듈러의 경우 동일 형태의 반복에 의한 유형과 서로 다른 형태의 결합에 의한 유형으로 구분될 수 있었다.

해양 플랜트의 관심의 증가로 사업의 수요가 많아지고 플랜트 사업이 상부구조물로서 경량체인 모듈러시스템을 상부구조물로서 적용된다면, 그에 따른 파랑하중을 적용시킨 모듈러시스템의 구조해석이 필요하다. 이 연구에서는 파랑하중이 모듈러시스템에 끼치는 영향을 알아보기 위해 구조해석 프로그램인 MIDAS를 사용하여 모듈러시스템에 정적하중과 조합하중의 모멘트를 비교 분석한다.

This study is about the case study on the application of modular system to the superstructure of floating architecture in Europe. There are many restraints in the onsite construction of floating architecture. Then, various industrialized construction methods are needed to reduce the portion of the onsite construction in floating architecture. Among the various industrialized construction methods, the modular system can be more suitable for floating architecture. At this background, this study analysed the European cases of the application of modular system and classified the types of applied modular system. As a result, this study could classify the three types of modular system, such as, building unit modular, space unit modular and planning concept modular, and define the characteristics of three types by comparing with each other.

By producing pre-engineered modular system in the factory, It is enable to expedite construction and can be distinguished from two types by the method resisting load. One is the open-sided modular system composed of beams and columns. The other is enclosed modular system composed of panels and studs. Of the modular systems, the open-sided modular system buildings the connection between modules are difficult due to closed member sections, and the overall strength is reduced as a result of local buckling. In this study, in order to solve these problems, a modular system with folded steel members filled with concrete are proposed. The capacity spectrum method presented in ATC 40 is used for seismic performance assessment of the proposed model structure and the structure with conventional steel members. The analysis results show that at the performance point of each model the number and rotation of plastic hinge formed in the proposed modular system are smaller than those in the conventional system. Based on this observation it is concluded that the proposed system with composite sections has superior seismic capacity compared with conventional system.

In this study, the performance of the support modular system, as substructure of the proposed sustainable-perpetual modular road system to reduce road construction time and maintenance costs was evaluated. A modular road system consisting of 4 support modular cross-beams with a lower curved surface was constructed on the test-bed. Six load cells and eight LVDTs were installed in the center part of two cross-beam support modular systems. Two loads, 50kN and 100kN, were applied to 15 points on the pavement slab to measure the load and displacement occurring in the modular road system. The measured displacements were less than 1 mm, so it is considered that there was no problem in the stability of the actual road. When comparing the two applied loads and the measured loads in the field test, it was considered that the load transmitted to the ground under the support modular system is very small. It is considered that the modular road system with the support modular system is applicable to the actual road site.

Modular construction is popular as a smart building system because it can shorten the construction period. This study proposed a precast concrete (PC) core system that can further shorten modular construction time. The system was developed and its structural performance was verified through computational analysis. The proposed PC core system is a complete PC construction method using dry bonding. The results of the study indicated that the proposed PC core system has structural stability and performance suitable for modular housing.

In this paper, we present a novel method of parallelization of the modular multiplication algorithm to improve time and space complexity on RNS (Residue Number System). The parallel algorithm executes modular reduction using new table lookup based reduction method. MRS (Mixed Radix number System) is used because algebraic comparison is difficult in RNS which has a non-weighted number representation. Conversion from residue number system to certain MRS is relatively fast in residue computer. Therefore magnitude comparison is easily Performed on MRS. By the analysis of the algorithm, it is known that it requires only 1/2 table size than previous approach. And it requires 0(ι) arithmetic operations using 2ㅣ processors.

In this paper, we propose a bit-sliced modular multiplication algorithm and a bit-sliced modular multiplier design meeting the increasing crypto-key size for RSA public key cryptosystem. The proposed bit-sliced modular multiplication algorithm was designed by modifying the Walter's algorithm. The bit-sliced modular multiplier is easy to expand to process large size operands, and can be immediately applied to RSA public key cryptosystem.
